In sports, a farm team, farm system, feeder team, feeder club, or nursery club is generally a team or club whose role is to provide experience and training for young players, with an agreement that any successful players can move on to a higher level at a given point, usually in an association with a major-level parent team. This system can be implemented in many ways, both formally and informally. It is not to be confused with a practice squad, which fulfills a similar developmental purpose but the players on the practice squad are members of the parent team.

The reserve clause, in North American professional sports, was part of a player contract which stated that the rights to players were retained by the team upon the contract's expiration. Players under these contracts were not free to enter into another contract with another team. Once signed to a contract, players could, at the team's discretion, be reassigned, traded, sold, or released.
